REQUEST FOR PUBLIC COMMENT ON HIGH PERFORMANCE FORTRAN

To: The High Performance Computing Community

Invitation:

The High Performance Fortran Forum (HPFF), with participation from over 40 
organizations, has been meeting since January 1992 to discuss and 
define a set of extensions to Fortran called High Performance Fortran 
(HPF). Our goal is to address the problems of writing data parallel 
programs for architectures where the distribution of data impacts 
performance. While we hope that the HPF extensions become widely available, 
HPFF is not sanctioned or supported by any official standards organization. 
At this time, HPFF invites general public review comments on the initial 
version of the language draft. 

The HPF language specification, version 1.0 draft, is now available. This 
document contains all the technical features proposed for the language. 
We plan to make minor revisions to correct errors or clarify
ambiguities in March 1993, at which time we will issue a final draft;
however, we expect that there will be few (if any) major technical
changes from this draft.

HPFF invites comments on the technical content of HPF, as well as on the 
editorial presentation in the document.  To facilitate incorporation
of comments into the final document, we ask that comments be sent
before March 1, 1993.
